JAMES A. HERRICK, OF rNEWARK, NEW JERSEY.

GAS-PRODUCER.

Application filed December 30, 1912.

T 0 all whom t may concern.'

Be it known that I, JAMES A. IeInRRIoK, a citizen of the United States of America, and resident of Newark, in thecounty of EssexY and State of New Jersey, (whose post-oflice address is 90 West street, New York, N. Y.,) have invented certain new and useful Improvements in Gas-Producers, of which the following is a specication.

This inventionV relates to improvements in gas producers or the like structures, and has particular reference to the arrangement of parts whereby a portion of the producer casing may be cooled as desired.

One of the objects of the invention is to provide a producer section with means surrounding it and whereby a cooling fluid, as air, may be caused to flow over the periphery of the section in a vertical direction.

Another object of the invention is to provide a producer section with a hollow lining affording a gas mixing chamber, the said section being furnished with a cooling jacket through which air or the like may be caused to travel in a vertical direction.

Other objects and aims of the invention, more or less broad thany those stated above, together with the advantages inherent, will be in part obviousI and in part specifically referred to in the course of the following description of the elements, combinations, arrangements of parts, and applications of principles constituting the invention; and the scope of protection contemplated will appear from the claims.

In the accompanying drawings which are to be taken as a part of this specification, and in which I have shown merely illustrative forms of embodiment of the invention: Figure 1 is a section on the line 1 1 of Fig. 3; Fig. 2 is4 a section on the line 2 2 of Fig. 1; Fig. 3 is a section on the line 3 3 of Fig. 1; Fig. t is a section on the line 4.--4 of Fig. 3; Fig. 5 is a section on the line 5 5 of Fig. 7; Fig. 6 is a section on the line 6 6 of Fig. 5; Fig. 7 is a section on the line 7 7 of Fig. 5; Fig. 8 is a section on the line 8 8 of Fig. 7 and Fig. 9 is a section on the line 9 9 of Fig. 7.

Referring now more in detailvto the drawingsI show in Figs. 1 and 5 a part of ay producer, comprising two superposed concentric sections 10 and 11, which sections are relatively rotatable, the upper section 10 being preferably iXed and the lower section 11 being caused to rotate in any suit- Specicaton of Letters Patent.

able manner, not shown. Between the two sections there is the usual water-seal 12. In the embodiments of the invention shown, the novel features of construction are mainly to be found in the upper section 10, which section is of familiar appearance in so far as it includes a cover portion 14 and an annular casing or shell 15, and preferably supported by it in a manner hereinafter explained is a lining 1G, preferably of brick or other refractory material, concentric with the section 10 and the section 11, and of such thickness that it appreciably overhangs the interior of the lower casing 11. In the form shown in Figs. 1 to 4 of the drawings, this lining is pierced vertically to provide a straightaway opening for a removable water-cooled poker 17, which is inserted through the cover-plate of the section 10 and extends through said section 10 and into the lower section 11 in such manner that the inner end of the poker will approach more or less closely the inner wall of the lower section as shown. When the poker is not in place, the outer end of the poke hole may be suitably capped in any preferred manner. The lower end of the opening for the poker is through a hollow ring 18, which denes the lower end of the lining 16. In practice I prefer to construct this hollow supporting ring in a plurality of segments which are bolted together as indicated at 19, so that the several segments of the ring are substantially independent of each other in their cooling functions, that is to say, there is no communication from one segment to the other for the cooling fluid which enters them. These segments are closed at their inner ends, and open at their outer ends, in registry with openings 20 in the shell of the producer section; and in order that air or other fluid entering the sections by way of openings 20 may pass up through the lining 16, I provide for each segment a'tube 21,' which extends through the lining 16 from the top thereof and rests at its lower end in a depressed annular seat or shelf 22 formed in the upper wall 24: of the segment. The upper end of this tube 21 is preferably controlledv by means of a valve such as shown at 25 whereby the end of the tube may be opened more or less or closed entirely as desired, thereby toV regulate the draft off air therethrough. For the sake of strength and rigidity, I may provide ribsQG at intervals horizontally and servingto space apart the top and bottom walls of the segment. The poke hole through the lining is preferably defined by a tube 27 extending from the upper end of the lining and resting at its inner end in an annular scat formed in the top wall of the segment through which the poker extends. 1f it is desired to hold the poker against vertical displacement this may be readily done as by means of a strap 2S passing over the end of the poker and secured to the cover-plate of section 10 as by means of bolts 29.

lilith the apparatus thus described it is evident that when the poker 17 is in place as shown in Fig. 1, and supposing that the lower section 11 is rotating, the poker will serve to prevent any accumulation upon the inner walls of the section 11 coming within the range of the poker. By means of the cooling ring 18 and the fines 21 leading therefrom vertically through the lining 1G, it is evident that the lining may be aircooled, the natural draft causing a flow of air into the openings 20 and out through the tubes 21. By reason of the independent control of the several tubes 21 through their valves 25, one segment of the ring may be caused to have a more considerable cooling effect than another, so that the several segments of the ring may be regulated in accordance with conditions within the producer. It is quite obvious that, if desired, I might provide some means for forcing cold air or other cooling fluid positively into the several openings 20 and out through appropriate lues 21, as for instance by providing a bustle pipe about the producer section 10 having communication with the several openings 20. Ordinarily, however, the ventilation induced by the natural draft will be suflicient.

The device shown in Figs. 5 to 9 inclusive is similar to that described above except that the lining 16 is hollow, to define an annular chamber 30, which has openings at intervals about the lower end of the liningas indicated at 31 whereby the gas from the interior of the producer may pass into said chamber, the exit of gas from the chamber being by way of an opening 3:2 at the upper end of the lining. rl`he construction of the supporting ring segments is correspondingly changed, so that the ends of the segments are joined at thefrear of the openings 31, in order that there may be no communication between the Ventilating flues 21 and the interior of the chamber 30. That is to say, each ring segment, considered in horizontal plan, is provided with constricted portions 34: which lie back of those parts of the lining containing the openings 31, and with an expanded portion 35 that extends under those portions of the lining which lie between adjacent openings 31, there being preferably six of said openings 31 and six ring segments. The sleeve for the poker is shown at 36, and is preferably attached at its lower end to the wall of a ring segment, as indicated at 87. The poker is water-cooled, removable, and adjustable as to extent of proj ection as in the other embodiment, and may similarly be held against vertical dislace- In'both of the devices herein shown I have.

provided an overhanging lining having a hollow supporting ring therefor made in segments, with openings from the outer air to the kinterior of the hollow segments, and vertical lines leading from the interior of the hollow segments through the lining, said flues being controllableat will; and I have also provided poke holes extending through the producer cover, the lining, and the supporting ring segment thereunder.

As many changes could be made in the above construction, and many apparently widely different embodiments of this invention could be made without departing from the scope thereof, it is intended that all matter contained in the above description or shown in the accompanying drawings shall be interpreted as illustrative and not in a limiting sense. It is also to be understood that the language used in the following claims is intended to cover all the generic and specific features of the invention herein described and all statements of the scope of the invention which, as a matter of language might be said to fall therebetween.

I claim- 1. A gas producer casing having an interior hollow lining providing an annular chamber having an opening to the interior of the casing and an openingto the exterior of the casing, a hollow ring connected to the casing and supporting said lining, said ring having an opening to the exterior of the casing, and vertical flues extending through the lining from said ring.

2. A gas producer casing having a hollow lining interiorly of the casing, said hollow lining being provided in its lower edge and at intervals with openings to the interior of the casing, and a supporting ring connected to the casing and extending beneath said lining, said ring having a cut-out portion for each of said openings of the lining.

3. In a gas producer, a casing having a lining, and a segmental ring connected to the casing and supporting said lining, each of said segments being hollow and having openings to the exterior of the casing, and a tube extending through the lining from the top and communicating with a segment.

4. In a gas producer, a casing having a lining, and a segmental ring connected to the casing and supporting said lining, each of said segments being hollow and having openings to the exterior of the casing, a tube extending through the ring from the top and communicating with a segment, and a poker tube extending through the lining and through one of said segments.

In witness whereof, I have hereunto signed my name in the presence of two witnesses.
